Make sure you also move the folders in your Documents though:

Documents\My Games\FINAL FANTASY XIV - A Realm Reborn

That folder contains all your hotbar settings, gearsets, etc. That one has to go back in the same place.
That being said, your documents folder can be anywhere and it'll work. FFXIV uses the relative location for the Documents library and not a direct path. BUT your screenshots folder IS stored as a direct path. So if you move the Documents library, you have to change the screenshots folder in-game.
